    Jeez, only other 45 magnum i've ever seen in the Uk belonged to some dude called Sweetpea who worked in the Drag Specialties warehouse in London. That was 40 fucking years ago too! Nice bike man!

    Thanks Hoghead, I saw Randy's Magnum in a mag back in the mid 70's & always thought it was the prettiest Harley motor that Harley never actually made...... EBay made it doable as 900 sporty parts are not common here.... there was & I think it's still about,a 45 lower with 350 Matchless topends on it in a featherbed frame as a Caff racer from over in Kent somewhere,use to see it at the Kent Showback in the 80's & 90's

    This was a good clue to get more info. I guess my biggest question is WHY ? The evo motor is such a good engine, why use a TC top end? This one has S&S cases.

    Re Fatvo. Alan Sputhe is gone, but in his words it gave you the best of both worlds. I've noticed Twin cams in two friends workshops with cam bearing and tensioner issues. Even seen gear conversions, not sure about how strong the cases are either. I never liked them from an aesthetic view point either.

    Thanks to whoever built this, for showing how beautiful a swing arm 4 speed can look.

    I think part of it was you used evo wheels and picked up a 1/4 inch pf stroke, big bore cylinders, worked out to 100 cubes, ease of single cam. I even found TC heads on ebay that had the push rod holes reworked, the angles for the push rods were a little weird.

    I like that swing arm shovel with akront/borriani 16 inch dirtcatcher rear rim. English front forks?

    I can't quite figure-reckon custom trees/yokes with early sporty lowers?

    yea Hoghead, that is the matchless top ended magnum that has been seen in and around Kent for the past 40 odd years, I believe the owner runs a classic bike speed shop or something, for many years it was a rat bike, but was done up nicely a few years ago.............. very nice Caff .......

    I love those things. The front brake is badass, too.

    I don't want to do that to mine. I'm happy putting around.

    But I do like to see what people do with these things. So creative.

    Think Irish Rich may have had something to do with this.

    Though my bikes go in a different direction I was blown away by this bike the first time I saw it in the Horse.

    I cross posted that Norton-Matchless-Magnum cafe on the local Norton club forum and the AJS-Matchless forum which should dazzle some, and offend most. THANKS for that! I enjoyed it.

    There is a local AMA vintage MX club called the Tacoma Ducks, Click image for larger version.

ID:	109147 and they run a event called "Dinosoar Daze" and 3 days of MX, Flat track and trials as well as a swap meet. For many years we got a LOT of matchless & AJS bikes racing because they sold more compy models in the Pacific NW than anywhere else in the world,, but for a while there was a guy racing a Featherbed frame with a HD 45 motor in it in MX and surprisingly fast. Not the best choice of frames for off road,,

    There is someone who built a BSA preunit 500 single with a Harley Ironhead top end, pix are around,, but always wondered how they did it. I have been playing around with the idea of using a EVO sporty- Buell top end instead but still working it out.

    Several locals have built magnums... ocal guy built a few over the years and used to call and was always looking for BSA Preunit and Semi unit trans parts to work with them as well as Norton Commando Clutches.

    HD 45s typically had a weak 3 speed tranny and limited you to slow speeds, so many swap in a Triumph, Norton or BSA trans, but to be really tricky you use a Preunit BSA box-54-63 with a semi unit BSA mainshaft and some bits 51-53, then a Norton Clutch from a Commando. This setup with the right clutch stack can give you a 2 finger clutch (See old britts tech page on how, and I have found mixing the brass friction plates with the surflex ones gives a good result).
    But the Norton runs a triplex chain and with some creative machine work can line right up with the HD engine sprocket.

    Another local guy, Martin "Ace" Doerfler, of "Aces garage" has built some too.
